Nfc: Vts: modify WriteInvalidAndThenValidCommand

Invalid Data packets are ignored by the NFC controller in case there
isn't an active RF Interface. The test expects response for the invalid
data packet without any active RF Interface. This patch modifies the
test to send an invalid command instead which will guarantee a response.

Test: run vts test
